The real cost of keeping a task manual: a calculator walkthrough
A walkthrough of the ROI calculator — the Australian working-week math, the indicative rates, and the costs the calculator deliberately leaves out.
The ROI calculator at /calculator exists to answer one question: how much is a manual task costing you per year, in directly attributable labour dollars?
That sounds simple. It is not quite, because the inputs have to be defensible and the math has to survive an ops manager who has been quoted nonsense before. This note walks through how the calculator works, what assumptions it uses, and — more importantly — what it deliberately leaves out. The costs it excludes are usually larger than the costs it includes.
The Australian working week, in hours
The calculator starts with a grounded view of a full-time Australian working year. The math is:
- 38 hours per week — the standard Australian full-time week
- 48 working weeks per year — after four weeks of annual leave
- 1,824 hours per FTE per year — 38 × 48
That is the denominator everything else divides into — the productive hours you actually get from a full-time staff member before public holidays, sick leave, training, or meetings. Some roles lose more; very few lose less.
Other calculators use 2,080 hours per year. That is the American fifty-two-week assumption, and it overestimates Australian FTE capacity by about twelve percent, which makes manual tasks look cheaper than they are. This calculator uses 1,824 because that is what you actually get.
The indicative hourly rate
The calculator uses a SCHADS-aligned indicative hourly rate as the default, because most of the time the person doing the manual work is on an award-covered or award-referenced wage. The rate is set to a realistic mid-band figure for an operational role — coordinator, administrator, payroll officer.
Override it if you know the exact wage. For clinicians or senior coordinators, use their loaded cost. For junior admin, the default is close enough.
“Loaded cost” means the hourly wage plus on-costs — superannuation, leave loading, workers compensation, payroll tax where it applies. A rule of thumb: multiply the base hourly wage by 1.25 to 1.3. The default already reflects a loaded rate, so if you enter a base wage, load it first.
Three worked examples
Here is the calculator applied to three common task shapes. Numbers are illustrative — pick your own rate and your own hours to make them real.
Example one: a daily 30-minute task
A coordinator spends thirty minutes every weekday on a recurring admin task — checking a handful of emails, updating a spreadsheet, forwarding something to payroll.
- Thirty minutes per day is 0.5 hours
- Over a 48-week year at five days a week, that is 0.5 × 5 × 48 = 120 hours per year
- At a loaded rate of, say, $55 per hour, the task costs around $6,600 per year
Six thousand dollars a year for a task that feels like nothing. Staff do not notice it because it is spread across two hundred and forty small interactions. The calculator notices it because it is doing the multiplication.
Example two: a weekly 6-hour task
A payroll officer spends six hours every pay week reconciling timesheets against the roster before running payroll.
- Six hours per week × 48 weeks = 288 hours per year
- At a loaded rate of $60 per hour (payroll is usually higher-banded), the task costs around $17,280 per year
This is the kind of task that owner-operators often try to live with because the payroll officer “just does it” and does not complain. The calculator flips that framing. Seventeen thousand dollars is a meaningful budget line. A build that cuts the reconciliation from six hours to two hours — a realistic target for a well-scoped automation — recovers more than eleven thousand dollars per year in labour time, which is cycled back into work the payroll officer cannot currently get to.
Example three: a monthly 2-day task
A compliance lead spends two full working days once a month assembling an audit evidence pack, reconciling training records, and chasing outstanding acknowledgements.
- Two days is roughly 15.2 hours (a full-time day is 7.6 hours)
- Over twelve months, that is 182 hours per year
- At a loaded rate of $70 per hour (compliance leads are usually senior), the task costs around $12,740 per year
Notice that this task looks smaller than the weekly payroll example on the calculator, but it is doing more strategic damage. Compliance leads are scarce, expensive, and spending their best thinking time on document hunting instead of actual risk assessment. The direct dollar figure understates the real loss.
What the calculator deliberately excludes
This is the part of the walkthrough that matters most. The ROI number the calculator produces is conservative on purpose, because every category of cost beyond direct labour is harder to defend with a number. That does not mean they do not exist. It means we leave them off the number to keep it airtight, and then list them here so you know what you are not counting.
Error cost
Manual tasks produce errors. Errors cost money downstream — reworked payroll, rejected claims, missed compliance deadlines, underpayments that become industrial issues. An automation that reduces the error rate substantially produces real savings that never appear in the labour-hour math.
A rough estimate: count the times in the last twelve months that somebody had to fix something because of a data entry or reconciliation error. Multiply by the time each fix took and any remediation cost. That is error cost, and it is almost always larger than the labour cost of the task that produced it.
Compliance risk
Some manual tasks are load-bearing for audit readiness. If they fail, the consequence is not “we spent extra time.” It is an audit finding, a remediation order, a funded-service payment clawback, or reputational damage. These are low-probability, high-impact events.
The calculator cannot price this. Do the thinking separately: “if this workflow fails during an audit window, what is the worst case?” Then weight against the probability that current manual controls prevent it. Almost always, the automation is worth far more than the labour it saves because it converts occasional catastrophic failures into predictable small costs.
Staff turnover
Owner-operators underestimate this most. The people stuck doing repetitive admin are disproportionately the ones who leave. Their replacement cost — recruitment, training, the productivity drop of an open role — is real and attributable. An automation that converts a dreary role into a meaningful one retains staff who would otherwise walk.
No clean formula exists, but a defensible approach: look at the replacement cost of one coordinator and ask whether this build preventing one resignation per year would be worth it. The answer is almost always yes.
Opportunity cost
Every hour on a manual task is an hour not spent on the work the person was hired for. For clinicians, that is billable client contact. For coordinators, relationship work that retains clients. For quality leads, actual risk assessment. The labour cost captures wages paid. It does not capture the revenue not earned or the value not delivered.
For revenue-generating roles, the opportunity cost of an hour of admin is often two or three times the direct labour cost.
Why the calculator stays conservative
The temptation with ROI calculators is to bake in every speculative benefit and produce a huge number that impresses the buyer. That is the first number a sceptical CFO crosses out. The point of the calculator is to produce a number you can walk into a budget meeting with and not have it challenged in the first two minutes.
Direct labour cost is defensible. The wider costs exist, they are often larger, and you should think about them — but separately, with your own estimates, rather than baking them into a number that is supposed to survive pushback.
Run your own task through the ROI calculator and see the number. If it looks worth acting on, the next step is the fixed-fee assessment at /services/assessment, which turns the number into a build plan.
